V3.2 Beta

Writing low-level stuff to squeeze a CPUs performance is fun, haven't really done this in anger for 30 years. Written my own SSE / AVX / AVX2 code for DotProduct, managed to beat Intel's performance library by a factor of two.
forum.sdr-radio.com

Performance enhancements, bug fixes and a new Continuum display.

Have a nice weekend everyone.

Just install. It'll overwrite as needed.

Seems not related to your SSE/AVX code.

OK,  Few questions:
  • 32-bit or 64-bit?
  • Which kit did you download: Microsoft, Dropbox or Webhost?
This 8could* be a bad download but it shouldn't have installed were that the case. Please go back to the 3.1 release.

64-bit from Microsoft.
Ok, I'll try another combo.
Gisle Vanem
 

Another thing I've never seen before is that the BugTrap GUI never manages to become the foreground window.

I can see it when I <Alt-Tab> among the top-windows. But it's always shadowed by your opening splash image.
But a huge (115 MByte) c:\temp\SDRConsole_error_report*.zip gets created eventually.

Installed the 64-bit version from DropBox. Same crash.
So running cdb -c g "SDR Console.exe" directly (disabling BugTrap), I got this call-stack:

Hi,

 

FYI. Installed V3.2 Beta, 64-bit, to my Win10. Everything works. Thanks! 😊

OK,

I can't handle these dumps you're providing - please show me a screenshot of the error window. I'm making a kit now, I'll archive everything so I can analyse the crash dumps.

It's the Goups.IO Markdown formatter that massacres the mark-up code. Collapses all \r\n onto \n or something.
The only screenshot I was able to get was this inside the BugTrap .zip:

Even v3.1 (build 2572) crashes for me now :-(

Sorry,

Had to go out. let's get rid of all files, so:

  1. Uninstall (select from the Windows menu)
  2. Make sure all files have been removed from the installation folder, usually: C:\Program Files\SDR-Radio.com (V3)
  3. Install.
  4. If you still have problems then make sure the redistributable kits are correctly installed, one of these files could be bad.
  5. Finally try a new identity. 
My gut feeling is a bad file on the system.

Run the installer and accept defaults except for the question about installing for everybody or just the current user. Otherwise all warranties expressed or implied are void and you get to clean up the mess.

Thank you Simon.

Have been putting the Continuum through its paces on some recorded files, and so far, works as advertised.   Much appreciated.

Simon,

For an idiot, please, what is Continuum and what is its purpose?

TIA,
Mark
Nick Hall-Patch
 

Groups.io has quite a good search function using a single term , Mark .   I just did a search on "continuum" in the  SDR-Radio group, and you can see the discussion that led to Simon's work on this.

Example (message 66053):

(from SpectraVue manual:  "A continuum display for measuring spectral power over the entire span and/or the peak power within the span.")

The power is a single value displayed over time. The span can be set from one Hz to the full span being monitored.  It's derived from the FFT displayed.


I remembered that one because I sent it in, hi.   But the whole discussion is laid out quite well on the groups.io web page.

best wishes,

Nick

Still the same crash. Running inside cdb it clearly shows that a NULL-pointer is called:

And I was able to get this call-stack from ProcessExplorer when BugTrap kicked in:

(Hope that Groups.io does not massacres the above Markdown this time).

Besides your uninstall.exe program is way to aggressive IMHO.

I had this directory layout:.
* f:\gv\dx-radio\SDR-Radio the v3.1 version that worked.
* f:\gv\dx-radio\SDR-Radio\v.3.2-beta the latest version that crashes.

Then running f:\gv\dx-radio\SDR-Radio\uninstall.exe wiped everything!
